Name of the Vulnerable Software and Affected Versions Augeas versions up to and including 1.8.0

Description The issue is caused by a heap-based buffer overflow due to improper handling of escaped strings. An attacker could send crafted strings that would cause the application using Augeas to copy past the end of a buffer, leading to a crash or possible code execution. This can be exploited by a remote attacker to execute arbitrary code or cause a denial of service by sending specially crafted strings.

Recommendations For Augeas versions up to and including 1.8.0, update to a version later than 1.8.0 to resolve the issue. At the moment, there is no information about other specific mitigation measures for this vulnerability.
